The video depicts the moment of launching an artificial sun developed by China.
Misbar has investigated the claim and found it to be misleading. It turned out that the video depicts the launching of a rocket at the Wenchang Spacecraft launch site in China.
The nuclear fusion reactor rocket was officially named the Experimental Advanced Superconducting Tokamak (EAST). In addition, the reactor "set a new record for sustained high temperatures after running five times hotter than the sun for more than 17 minutes," according to Chinese media.
